I just bought an 04 silverado 2500hd ext cab 4X4. 410 rear. what are the free/cheep mods to start with? also what should it run stock?

I do have a few thin gs i want to try like P&P t/b /maf etc. the stuff i did on my Z28

 

also what is the best sponsor to order truck parts from?

 

What engine?? 6.0l, 8.1, or Duramax??

 

Sounds like an 8.1 truck? There are alot of mods available for this motor - induction, exhaust, headers, computer programming, ported throttlebody, MAFs and bigger mods like ported heads, Comp Cams and superchargers if you feel that you need a big gain in horsepower.

I believe a stock HD runs in the high 15s to low 16s?

its the 6.0L

 

Steve,

One of the first things you should do would be to put on a UPD intake. I have an 04 Denali 6.0L and am pretty happy with what the UPD did for it.
I have been happy with the customer service I have gotten from Tbyre. Would definately recommend Tom for any performance products you want to get for the new truck.

Open up the intake and exhaust. it is well worth it. Then get tuning.

 

Steve,

When you get a chance could you check your exhaust and let me know what the configuration on it is. Mine is dual 3" in and out of the muffler with the y-pipe behind the muffler. Seems like an odd way to do the exhaust just wanted to see if yours was the same.

Thanks,

Kevin

 

Yeah tuning for sure...the 6.0s are the most detuned of all the truck motors from what I have heard.

 

Is Edit available for the 04's yet??
